Oil Questions
We are about to fire up the engine and I have some questions on engine oils.
Engine is a 327 with a hyd. retro roller rocker cam.
1. Best break in oil?
2. Since it's a roller cam do I need to worry about zddp for break in and normal use?
3. If we run the engine for 30-45 mins from 2k-3k rpm will that suffice as break in time and seat the rings?
4. After break in, go synthetic or dino based oil?
5. Best weight for a 400ish HP sbc where climate ranges from 20's to high 90's?
